Reaction Steps

A mixture of 2-Cyanomethyl-4-methoxy-5-(2-methoxy-ethoxy)-benzoic acid (1.0 g, 3.77 mmol), 3-amino-5-methylpyrazol (0.73 g, 7.54 mmol) in acetic acid (10 ml) were sealed in microwave process vial (20 ml). The mixture was heated at 130° C. for 30 minutes under microwave irradiation. After removal of acetic acid, the residue was dissolved in 2 ml MeOH. This solution was added dropwise to 100 ml water, and the solid was collected and dried to give product (0.8 g, 61.6%). LC-MS: m/e 345 (MH+).
